Bad service and slow service

went in the bank and there was no one to assist me with where i should go for collections and i asked some consultant who was busy with a client and she directed me to the Que, and after i stood on the long Que where there was only one consultant available to assist with collections and statements. when i got to the consultant then she told me im on the wrong que and the guy who assist customers que comes to me and he just asked me \who told you to stand on this line without any greetings and they wanted me to go Que on other and i have to fill in some documents and i app**** for my card online and there was a guy who came to delivers and there was no documents to be filled and out of no where i have to wait for documents and i just left the branch as it was also too hot in that branch there air-con was not working"
